Is Sea Level Rise Accelerating In The Chesapeake Bay? A Demonstation Of A Novel New Approach For Analyzing Sea Level Data, Tal Ezer, William Bryce Corlett

CCPO Publications

Sea level data from the Chesapeake Bay are used to test a novel new analysis method for studies of sea level rise (SLR). The method, based on Empirical Mode Decomposition and Hilbert-Huang Transformation, separates the sea level trend from other oscillating modes and reveals how the mean sea level changes over time. Bootstrap calculations test the robustness of the method and provide confidence levels. The analysis shows that rates of SLR have increased from similar to 1-3 mm y(-1) in the 1930s to similar to 4-10 mm y(-1) in 2011, an acceleration of similar to 0.05-0.10 mm y(-2) that is …

The Ross Sea, the most productive region in the Antarctic, reaches farther south than any body of water in the world. While its food web is relatively intact, its oceanography, biogeochemistry, and sea ice coverage have been changing dramatically, and likely will continue to do so in the future. Sea ice cover and persistence have been increasing, in contrast to the Amundsen-Bellingshausen sector, which has resulted in reduced open water duration for its biota. Models predict that as the ozone hole recovers, ice cover will begin to diminish. Currents on the continental shelf will likely change in the coming century, …
